Welcome and thanks for posting your query to HCM.
I can make out from your problem that the things are definitely bit overdone. The very important thing is Fraxel
laser is either done by the doctor or is done in presence of doctor- what was your situation??
Now for the blister
you have don't try any other method or advice as you have blister formation which can any time get infected. To my advice under medical supervision and aseptic precaution it should be punctured, fluid drained and the underlying skin should be reposited back as covering with proper oral and topical antibiotic
coverage. This is very important to keep in mind that you MUST consult and visit the laser doctor as soon as possible to show your condition as technician is not your dermatologist
/ laser doctor. It is practically very difficult by any method of treatment to make it perfect in just two days. In between you can apply calamine
lotion and antibiotic cream with cold compression to prevent further aggravation.
Get well soon,
Dr Sanjay K Kanodia
